ElementUSA and Colorado School of Mines Awarded $67m by DOE for Construction of Rare-Earth Processing Plant

Why It Matters

The funding accelerates domestic production of rare‑earths and other critical minerals, reducing reliance on foreign sources and turning an industrial waste stream into a strategic asset for advanced manufacturing and national security.

Key Takeaways

• DOE grants $67 m to build REE plant in Louisiana
• Process turns bauxite residue into pig iron and 15-plus critical minerals
• Facility aims 1 M t/yr feed, $1.1 bn capex, 45‑385% US REE demand
• Exclusive access to 34 M t of residue offers strategic waste-to‑resource model

Pulse Analysis

The United States has intensified its push to secure domestic sources of critical minerals, a move driven by supply‑chain vulnerabilities exposed in recent years. By awarding ElementUSA and the Colorado School of Mines a $67 million DOE grant, the government is betting on a novel waste‑to‑value approach that transforms bauxite residue—a by‑product of aluminum refining—into a diversified portfolio of rare‑earth elements, gallium, scandium and other high‑tech metals. This partnership blends ElementUSA’s commercial scaling capabilities with CSM’s world‑class mineral‑processing research, creating a credible pathway from laboratory validation to full‑scale production.

At the heart of the project is a hybrid hydrometallurgical and pyrometallurgical flow sheet that co‑produces pig iron while extracting more than a dozen critical metals. The technology’s ability to generate revenue from both iron and high‑value REEs improves unit economics and cushions the operation against price volatility that typically plagues single‑commodity mines. With an exclusive lease on roughly 34 million tons of Louisiana residue, the plant could meet up to 385% of U.S. annual demand for certain rare‑earths, positioning the site as a unique, polymetallic resource that rivals traditional ore deposits.

Commercially, the initiative is expected to catalyze long‑term offtake agreements with defense contractors, semiconductor manufacturers and specialty material firms, unlocking financing for the projected $1.1 billion full‑scale facility. Beyond the immediate economic upside, the project addresses a massive environmental challenge by repurposing a waste stream that would otherwise occupy land indefinitely. If successful, the model could be replicated at the estimated 4 billion tons of global bauxite residue, reshaping the critical‑minerals landscape and bolstering U.S. strategic autonomy.
